AGlTATOR FOR MIXED ^PAlNTS.

SPECIFICATION forming part of Letters Patent No. 510544, dated December 12, 1893.

Application filed February 28, 1893. Serial No. 464 126 (NO model.)

To all wwm it may concern:

Be it known that I, CHARLES JOHN MOLEN- NAN, manufacturer, of the city'ot' Toronto, in

the county of York, in the Province of Onta-' 5 rio, Canada, have invented certain new and useful Improvements in Agitators for Mixed Faints, of which the following is a Specifica- My invention relates to improvements in IO agitators for mixed paints, and the object of the present invention is to provide an alternative means whereby the sediment which settles at the bottom in paint already mixed may be prevented from settling and stirred :5 up into the main body of the paint and it consists essentially of providing in the bottom of the receptacle or tank in which the mixed paint is placed a perforated main tube and perforated branch tubes extending outwardly therefrom at the bottom of the receptacle, the main tube being connected by a universal or swing joint to the end of the barrel of a pump, which is operated so as to draw continually from the paint near the surface and force it through the perforations of the main tube and branch tubes at the bottom of the receptacle as hereinafter more particularly explaiued.

The drawing represents a perspective view of a paint receptacle, a portion of the side being broken away and a portion of the pump being in section so as to exhibit the arrangemont and operation of my invention.

A, is the receptacle,which is partially filled with mixed paint as shown.

B, is the main tube located preferably centrally at the bottom of the reoeptacle and having extending outwardly therefrom also preferably in proximity to the bottom the branch tubes, O. The branch tubes, C, are perforated on each side and have caps at the ends which are also perforated as shown and the main,

tube is perforated also at each side and has caps at the end Which are also perforated as shown. The outer 'ends of the branch tubes are preferably braced by the wires or rods,

D, which extend around near the outside of the same as shown. The inner 'end of the main tube has an are-shaped end, b, which 5 fits within the are-shaped end, e, of the pumpbarrel, E.

F, is an opening made in the side of the pump-barrel considerably beneath 'the surface of the paint. As the surt'ace of the paint as shown in the drawing, in which the receptacle is only partially filled, is indicated by the curved dotted lines 1--2 it will be seen that the opening F, is below the surface of the paint and it will of course be understood that the Opening, F, is always beneath the surface of the paint. The opening, F, is provided with a netting, f, to prevent the entrance of any foreign substance in the paint into the pump.

G, is the 'piston Which is provided with the usual opening, g, and valve, g'. The piston, G, is fastened on the forked end of the piston rod, H. At the upper end of the piston rod, H, I secure the guide, I, to which is attached the lower end of the connecting rod, J. The upper end of the connecting rod, J, is secured to the end of the Crank, K, attached to the main driving spindle, L, which derives motion from the pulley, M, driven from any suitable motor.

N, is the piston valve which is situated at the lower end of the barrel, E.

O, is a cord or chain which is attached to an eye at the top of the cap at the end of the main tube, B. The upper end of the cord is fastened to a cleat.

It will be seen as usual in pumps that upon the upward stroke of the piston the pump valve will be closed while the valve in the piston Will be open and the mixed paint from the receptacle Will flow through the same in between the piston and the valve, and upon the downward stroke of the piston that the valve, N, will be Open and the piston valve closed so that the liquid will be forced down through the barrel into the main tubes and branch tubes where it will be forced through the perforations all around the bottom of the receptacle thereby tending by the continual working of the pump to keep the sediment stirred up in the bottom of the receptacle and thus keep the mixed paint of a uniform thickness throughout. It will of course be understood that the mixed paint is intended to be used for dipping.

When it is not desired to use the paint and the pump is stopped from working the main tube being swung in the' arc shaped bottom TOO end of the piston barrel may be raised by the cord, 0, so that the main tube and branch tubes will be raised up into the top of the paint away from the bottom, and thus any danger of the holes being filled by the sediment willbe avoided. Again although I show the tubes in the form shown it will of course be understood that other forms of tubes or their equivalents with perforations therein might be devised to aecomplish the same result as the main and branch tubes and I wish it to he understood that I do not wish to be cOnfined to the eXact form of perforated main tubes and branch tubes shown. 4

Although I show the arc-shaped end, b, of the tube, B, fitting into the arc-shaped end, e, of the barrel, E, it will of course be understood that other forms of Couplings might be devised, which will accomplish this result that is to say which Will enable me to raise the tubes from the bottom of the tank out of the sediment, which would otherwise form if left there, when the pump is not in motion and the paint is not being used.

What I claim as my invention is-- In combination with a reeeptacle for mixed paints adapted for use for dipping articles therein, means for agitating and keeping the contents stirred consisting of perforated distributng tubes arranged On the bottom thereof, and a pump for forcing the material through the distributing pipes, located near one side of the tank, whereby the interior of the said tankis practically unobstructed and free for the dipping of articles in the paint contained therein, substantially as described.
